Nice to see these at the project stage.
I would prefer too see it released as two separate kits of two versions. One sprue of generic parts for the 234 and the extras pieces on sprues B 234/1 and 2, sprue C for 234/3 and 4. Plus a crew sprue.
I see the PUMA graphic does not have the stowage box on the rear fender next to the aerial mount, it only seems to be unique to some 234/2 photos that I have seen.
There also seems to be different designs of tyers as the war progressed, possibly salvaged from other vehicles as needed.
I am not too sure of the other variants planned of the Luches turm or the 20mm schwebelafette as I have only seen these as models. I have not seen any photos of them, I hope someone has info of these variants. However, the 20mm fgst would be useful in making a 251/17D.
Sometime next year I would like too see the 232s, although I am not interested in the Lee/Grant I am sure if it does appear a Priest will surely follow.
